Wanted to share this information to women who suffer from persistent allergic rhinitis, sinus congestion and who get frequent sinus headaches and sinus infections...I tend to prefer all natural products to relieve my health ailments. Didn't think I had allergies but when the pollen and mold counts surge by 300% It's hard not to be hit by allergies. I have been using Sinol-M, an all natural nasal spray since April of 2009. I am happy to report that since using this OTC product my allergy symptoms are gone and I did not get my typical spring sinus infection and it appears that I'll sail through the fall season without one too. Sinol-M has been keeping my nasal passages clean, clear and free from bacteria. I no longer have sinus headaches or congestion. There are no side effects and I love the fact that its not harmful to me. I honestly am so happy that it works. Sometimes with natural products you can't really feel/see the benefits but I have to say that with Sinol-M its evident and I'm thrilled. Anyone suffering from allergies/sinus or headaches should give it a try. Rite Aid pharmacies, Path Mark, WholeFoods carry it and you can get more info from www.sinolusa.com
